+# SYNOPSIS
+#
+#   AX_BOOST_LOCALE
+#
+# DESCRIPTION
+#
+#   Test for System library from the Boost C++ libraries. The macro requires
+#   a preceding call to AX_BOOST_BASE. Further documentation is available at
+#   <http://randspringer.de/boost/index.html>.
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_LOCALE_LIB)
+#
+#   And sets:
+#
+#     HAVE_BOOST_LOCALE
